None of these stories are to be found in the work of Geoffrey of Monmouth, who had written earlier in Latin, nor in any of the so-called chronicles. It was Chrétien who took the old folk-tales that men had been telling each other for centuries and put them into sprightly verse for the entertainment of his lords and ladies. He fashioned the stories according to the taste of his own gay courts, and so Arthur and his Queen Guinevere, Lancelot, Perceval and the other knights became far more like French people of the twelfth century than like Britons of the sixth. And in introducing the Holy Grail, that sacred and mystic cup that was supposed to hold drops of the blood of Christ and to have been carried to England by Joseph of Arimathea, Chrétien added to the Arthurian legends an old religious story that had had nothing to do with Arthur originally. From this point in its history that sturdy ancient English oak, the original story of Arthur and his knights, an account mainly of warlike adventures, sent forth four new branches that have now become part and parcel of the parent legend. These four branches are the story of Merlin, the story of Lancelot, the story of the Holy Grail, and the story of Tristram and Iseult. Some of the writers who came after Chrétien took one of these stories, some another, each enlarging his theme according to his own taste, until each story was the center of a large number of new and romantic offshoots. Practically all of them, however, were bound together by the thread that led from the court of the great King Arthur at Camelot. The story of Merlin, that man of magic, is the least important of the four branches, though Merlin is still an intensely interesting figure in the story of Arthur that we read to-day. The story of Lancelot was to prove very important; starting as a romance that had very little connection with Arthur, it became with Malory and Tennyson the real center of interest of the plot. The story of the Holy Grail proved almost equally important. In the earliest accounts of this Perceval was the knight chosen above all others to reach the Grail Castle, but Perceval was too rough and worldly a knight to suit the taste of the monks who wrote out the legends and so they created Galahad to take his place as their own ideal of perfection. And into these adventures are woven some of the tales of Sir Gawain, among them the delightful story of Gawain and the Little Maid with the Narrow Sleeves. To the legend of Perceval, Wolfram von Eschenbach, a Bavarian, added the story of the son of Perceval, or Parzival, as he calls him, the story of Lohengrin, the famous Swan-knight. Tristram and Iseult, the fourth of the branches, though less connected with Arthur than either Lancelot or the Holy Grail, became immensely popular with poets and remancers because of its great love story, and is to be found told again and again in widely varying forms all through the Middle Ages.
